in reply to Getting an IP address from DHCP

Is there a way for a box behind a firewall to tell what IP address the firewall is using, and more to the point, is there a perl module that anyone has experience using that can divine this info elegantly.

I have a similar setup. The way I deal with it is described in this post. Basically, it involves pinging a CGI on my external website periodically, and remembering the remote IP address (i.e., the one assigned to my router by my DSL provider).
